How to getSimOperator in dual SIM phone android?

[Hitesh Matnani]

I am building an android application where I need a value of "getSimOperator".

I am able to get this value > 21 API version but for the lower version in dual SIM. I am getting a value of SIM1 but not able to get SIM2 value.

How can I get "getSimOperator" value of SIM2 < 21 API version.

I earlier posted a question below is the link How to get Mcc and Mnc below LOLLIPOP_MR1 devices in android? - Stack Overflow.

Someone has referred me a link http://stackoverflow.com/questions/32707158/dual-sim-android-phone-which-sim-receive-a-call/32871156#32871156.

But I am getting an error while implementing the code of above link. I had listed down the error "java.lang.NoSuchMethodException: getDefault [int]"

Cloud anyone explains me why this error is coming.
